YANKTON, S.D.(WNAX)- Summit Carbon Solutions and the Navigator pipeline are both working on right of ways across a number of counties in South Dakota. Both would carry liquid carbon dioxide from ethanol plants to underground storage sites.

Landowners are concerned about the use of eminent domain to first survey the routes, then lead to possible construction.

Brian Jordre, a lawyer representing a number of landowners, says the concern is rising.

Jordre says Summit Carbon Solutions has started condemnation proceedings in some areas.

Jordre says there is a constitutional court case in front of the South Dakota Supreme Court.

The Public Utilities Commission will hold hearings on the Summit application in September and Navigator in November.
